Advanced TIG Controls

Pulse TIG Welding
Fine-tune arc characteristics with adjustable pulse duty and frequency (0.5–200 Hz). Control weld bead shape, penetration, and heat input for professional results.

AC Balance Feature – Removes Oxidation and Impurities
Adjust the AC cycle to clean oxidation and stir impurities from the weld puddle, producing stronger, cleaner aluminum welds.

High-Frequency Arc Start
Ignite the arc without touching the workpiece for precise, contamination-free starts.

Customizable Arc Parameters

• Start/end current tapering

• Up/down slope control

• Background current settings

• AC frequency adjustment (40–200 Hz)

Stick Welding Made Simple

Stick Mode for Quick Action
Flip a switch to move from TIG finesse to fast, rugged DC Stick welding up to 180 amps — perfect for fencing, equipment repairs, and outdoor jobs.

Electrode Anti-Sticking
Prevents rods from freezing to the workpiece, keeping jobs moving smoothly.

Quality Accessories
Includes a 10-foot stinger clamp for maximum reach and usability.
